The market has a powerful incentive to continue heading higher, even after its remarkable run, and Jim Cramer expects analyst recommendations to weigh in significantly for the rest of the year.

Usually analyst opinions don't sway the direction of the stock market. But in moments like these, Cramer says investors should anticipate analyst recommendations, because the opinions will have the potential to move the market.

"We are in the sweet spot where analyst upgrades can make any stock roar higher. Now that you see how the game is played, you need to 'get some,'" the "Mad Money" host said. "I think there will be plenty more of these to come in the last two weeks of the year."

Disney moved higher on Monday after Bank of America Merrill Lynch put the company on its "U.S. 1" list. Analyst Jessica Reif Cohen cited that they like Disney's growth, has stable-to-low growth media networks and a solid studio outlook for its major labels like Pixar and Marvel.

What really stood out for Cramer was the lack of any emphasis on ESPN from Cohen. All of these strong initiatives existed when Disney's stock tumbled to $88 in February from $120 a year ago. They were simply overshadowed by fears of declining ESPN subscriptions.

"In short, it doesn't seem to matter anymore … the worry that once crushed this stock is now in the rear-view mirror without any mitigation of those subscriber losses," Cramer said.

Cramer also saw the same action play out for Costco on Monday. Citigroup upgraded the stock, thanks to a membership fee increase that could be coming and a special dividend next year, along with the possible end of gasoline, food and tobacco deflation.

There was nothing in the research note that Cramer hasn't highlighted himself. Yet, it didn't seem to matter.

"Costco, like Disney, is still well off its highs. It has a good story. It's marked time. It was ripe for an upgrade and it got one," Cramer said.

Cramer was also shocked by the upgrades of United Technologies, General Electric and Nvidia. Especially Nvidia, as it was upgraded by Loop Capital. Cramer said he had never even heard of Loop Capital before, yet somehow it managed to be a catalyst and lift the stock.

"I'm on the verge of sensing a series of upgrades for Nike, although I still expect it to report a disappointing quarter tomorrow night. It would be pure gun jumping, but I think Nike could report a not-so-hot quarter and still catch upgrades," Cramer said.
